Description

Technical Field

[0001] The invention relates to the technical field of sewage sludge separation, and in particular to an integrated device for sewage sludge separation and treatment. Background Art

[0002] With the acceleration of urbanization and the tightening of environmental protection standards, the challenge of sludge separation during sewage treatment is becoming increasingly prominent. Traditional sludge treatment equipment, which generally uses centrifugal separation, belt filter presses, or plate and frame filter presses, faces technical bottlenecks such as easy filter clogging, short cleaning cycles, high energy consumption, and low solid-liquid separation efficiency.

[0003] Especially during the dynamic filtration process, sludge particles tend to adhere and deposit on the surface of the filter, causing the filtration efficiency to significantly decrease with the operating time, requiring frequent shutdowns for manual cleaning, which seriously restricts the treatment efficiency. Although the existing technology attempts to improve the filter clogging problem through high-pressure backwashing or vibration slag removal, it has the defects of surging energy consumption, complex structure, and inability to achieve separation and self-cleaning simultaneously. In addition, traditional equipment has poor adaptability to sludge concentration fluctuations, and is prone to mechanical overload under high solid content conditions, making it difficult to meet the continuous and intelligent operation requirements of sewage treatment plants. For this reason, there is an urgent need to develop a sludge treatment device that integrates dynamic separation, real-time self-cleaning, and load adaptation to break through the structural limitations and efficiency bottlenecks of traditional equipment. Summary of the Invention

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0006] The present invention provides an integrated device for sewage sludge separation and treatment, comprising a base frame, a separation barrel rotatably mounted on the base frame, a filter assembly mounted on the separation barrel, and a drive mechanism for intermittently driving the separation barrel to rotate forward and reverse;

[0007] The center position of the bottom wall of the separation barrel is provided with a protrusion protruding toward the inside of the separation barrel, and the protrusion forms an inwardly concave drainage groove at the bottom of the separation barrel, the protrusion includes a columnar portion coaxial with the separation barrel and a filtering portion uniformly connected to the outer periphery of the columnar portion along the circumferential direction and extending radially, and the filtering portion decreases in width from one end to the other end of the columnar portion to form a tip structure, drainage ports are provided on both sides of the filtering portion, the drainage groove forms a water collecting trough with a circular cross section corresponding to the columnar portion, and the drainage groove forms a drainage trough with an isosceles trapezoidal cross section corresponding to the filtering portion;

[0008] The filter assembly includes a filter screen installed at the drain outlet and a sealing component fixed on the base frame. The sealing component includes a first sealing portion that is tightly attached to the inner wall of the water collection tank and a second sealing portion that is tightly attached to the bottom wall of the separation barrel. During the rotation of the separation barrel, the sealing component can intermittently and synchronously block the bottom opening and side opening of the drainage trough through its first sealing portion and second sealing portion, thereby blocking the drainage path of the water collection tank.

[0009] Furthermore, the separation barrel is rotatably assembled on the base frame through an upper thrust bearing and a lower thrust bearing. A limiting ring is provided at the top of the outer wall of the separation barrel. The upper thrust bearing is provided between the top of the limiting ring and the base frame, and the lower thrust bearing is provided between the bottom of the separation barrel and the base frame.

[0010] Furthermore, the driving mechanism includes a driving shaft fixedly mounted on the top of the protrusion and coaxial with the separation barrel, and a driving source transmission-connected to the driving shaft. The top end of the driving shaft extends from the top of the separation barrel and is rotationally connected to the base frame, and the driving source is fixed on the base frame.

[0011] Furthermore, a fixed support shaft is coaxially arranged in the water collection tank, the bottom end of the fixed support shaft is fixedly connected to the base frame, the top end of the fixed support shaft is rotatably connected to the top wall of the water collection tank through a bearing seat, and the blocking member is fixed to the fixed support shaft through a connecting piece.

[0012] Furthermore, sludge storage components are evenly arranged on the outer wall of the separation barrel along the circumferential direction, and the sludge storage components are arranged corresponding to the filtering part. A sludge storage cavity extending along the height direction of the separation barrel is formed in the sludge storage component, and a strip-shaped slit is provided between the sludge storage cavity and the separation barrel. A scraper is also provided in the separation barrel, which is close to the inside of the separation barrel. The top end of the scraper extends from the separation barrel and is fixedly connected to the base frame.

[0013] Furthermore, the cross section of the strip-shaped slit is tapered, and the small opening end of the strip-shaped slit faces the sludge storage cavity.

[0014] Furthermore, the sludge storage component includes a cylindrical shell, the sludge storage cavity is formed in the cylindrical shell, a honeycomb-structured column is placed in the sludge storage cavity, and an openable and closable airtight door is also provided on the outer wall of the cylindrical shell.

[0015] Furthermore, a cover with a through hole in the center is detachably mounted on the top of the separation barrel, a liquid collecting trough is provided at the bottom of the base frame corresponding to the drainage groove, and a drainage pipe is provided on one side of the liquid collecting trough.

[0016] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. This invention utilizes a dynamic filtration unit formed by a tilted filter screen with a protruding portion, combined with intermittent forward and reverse drive and the synergistic effect of a blocking component, to achieve centrifugal separation, dynamic blocking, and reverse flushing cycles. While the upstream side efficiently filters, the reverse liquid flow automatically strips away sludge adhering to the filter screen on the downstream side, overcoming the problem of traditional equipment's filter screen being easily clogged and requiring manual cleaning.

[0018] 2. The present invention switches the rotation direction at preset cycles through the drive mechanism, allowing the upstream and downstream sides of the filter unit to swap roles, forming a two-way alternating cleaning mechanism. Combined with the flow guidance design of the isosceles trapezoidal drainage trough, it ensures that the self-cleaning process can be triggered after each turn, extending the service life of the filter.

[0019] 3. The tapered strip slits of the sludge storage assembly of the present invention are combined with the honeycomb structure column to accelerate sludge enrichment by using the centrifugal force field. The synergistic effect of the dynamic scraping of the scraper and the high shear slits achieves the breakup and orderly migration of sludge agglomerates, improves the sludge dehydration rate, and avoids sludge accumulation on the side walls of the separation barrel.

[0020] 4. The servo motor of the present invention is combined with variable frequency speed regulation technology and a two-stage reduction gearbox to automatically match the speed and torque according to the solid content of the sludge. For example, when the solid content is greater than 20%, the separation is enhanced at a high speed of 1000 rpm, and the frequency is reduced to 600 rpm under low concentration conditions, thereby reducing overall energy consumption.

[0021] 5. The dual-layer thrust bearing and fixed support shaft form a bidirectional restraint system that effectively disperses centrifugal force and dynamic pressure, ensuring smooth operation of the separation barrel under high loads. The modular design of the sludge storage assembly and the airtight door support rapid desilting and maintenance.

[0022] 6. The compression and dehydration effect of the honeycomb structure column on sludge can also reduce the cost of subsequent drying treatment.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] See also Figures 1-6 The present invention provides an integrated device for separating and treating sewage sludge, comprising a base frame 1, a separation barrel 2 rotatably mounted on the base frame 1, and a filter assembly 3 (such as Figure 3 As shown), and a driving mechanism 4 for intermittently driving the separation barrel 2 to rotate forward and reverse;

[0035] Combine Figure 3 、 Figure 4 and Figure 5 As shown, the center of the bottom wall of the separation barrel 2 has a protrusion 5 protruding toward the inside of the separation barrel 2 (as shown in FIG. Figure 4 As shown), the protrusion 5 forms a concave drainage groove 51 at the bottom of the separation barrel 2 (as shown Figure 5As shown), the protrusion 5 includes a columnar portion 52 coaxial with the separation barrel 2 and a filtering portion 53 uniformly connected to the outer periphery of the columnar portion 52 along the circumferential direction and extending radially, and the filtering portion 53 has a width that continuously decreases from one end to the other end of the columnar portion 52 to form a pointed structure, and a drainage port 54 is provided on both sides of the filtering portion 53. The drainage groove 51 forms a water collecting trough 511 with a circular cross section corresponding to the columnar portion 52, and the drainage groove 51 forms a drainage trough 512 with an isosceles trapezoidal cross section corresponding to the filtering portion 53;

[0036] like Figure 6 As shown, the filter assembly 3 includes a filter screen 31 installed at the drain outlet 54 and a sealing member 32 fixed on the base frame 1. The sealing member 32 includes a first sealing portion 321 that is tightly attached to the inner wall of the water collection tank 511 and a second sealing portion 322 that is tightly attached to the bottom wall of the separation barrel 2. During the rotation of the separation barrel 2, the sealing member 32 can intermittently and synchronously block the bottom opening and side opening of the drain tank 512 through its first sealing portion 321 and the second sealing portion 322, thereby blocking the drainage path of the water collection tank 511.

[0037] This device constructs an annular filtering flow field in the separation barrel 2 through the columnar part 52 of the protrusion 5, which can serve as the initial channel for the convergence of the sludge mixture, and the filtering part 53 of the protrusion 5 forms a dynamic filtering unit by tilting the filter screen 31. When the driving mechanism 4 starts the separation barrel 2 to rotate, the sludge mixture is quickly stratified under the action of centrifugal force, that is, the solid particles with higher density are enriched radially toward the side wall of the separation barrel 2, significantly reducing the amount of sludge attached to the filter screen 31, and the liquid impacts the inclined filter screen 31 on the upstream side of the protrusion 5 along the tangential direction of rotation. The filter screen 31 is arranged obliquely, and while increasing the effective filtering area, it uses the normal component force generated by the liquid flow impact angle to accelerate liquid penetration, so that the liquid flows into the drainage groove 512 with an isosceles trapezoidal cross-section through the drainage port 54 and is quickly discharged through the bottom opening, thereby improving the filtration efficiency. In this process, the filter screen 31 on the backflow side only plays an auxiliary drainage role due to the misalignment of the liquid flow direction, but its structural design lays the groundwork for the subsequent self-cleaning stage.

[0038] As the separation barrel 2 continues to rotate, the double sealing parts (the first sealing part 321 and the second sealing part 322) of the fixed sealing member 32 will continuously interfere with the drainage trough 512 as the separation barrel 2 rotates. That is, as the separation barrel 2 rotates, the sealing member 32 synchronously closes the bottom and side openings of the drainage trough 512 distributed in the circumferential direction in an intermittent rhythm, blocking the drainage path of the water collection tank 511. When the drainage path of a certain water collection tank 511 is blocked, the liquid is forced to turn to the filter screen 31 on the backflow side of the water collection tank 511 for discharge. At this time, the liquid that has passed through the filter screen 31 on the upstream side passes through the filter screen 31 on the backflow side in the opposite direction, forming a strong reverse flushing from the outside to the inside to peel off the sludge attached to the surface of the filter screen 31 on the backflow side; the peeled sludge migrates along the inclined surface of the filter screen 31 toward the side wall of the separation barrel 2 under the action of centrifugal force, avoiding secondary deposition. This dynamic blocking-reverse flushing action can achieve real-time cleaning of the filter screen 31.

[0039] When drive mechanism 4 switches rotational direction according to a preset cycle, the previously active drainage side and the backflow side swap roles. Reverse rotation causes the previously cleaned filter unit to transition to the frontflow side for primary filtration, while the previously active side initiates self-cleaning through reverse flow, creating a bidirectional, alternating cleaning design. Through the precise coordination of intermittent forward and reverse drive and blocking member 32, the device cyclically executes the "centrifugal separation - dynamic blocking - reverse flushing - path resetting" process, improving separation efficiency while overcoming the pain points of traditional equipment, such as easy filter clogging and manual cleaning, through structural innovation.

[0040] like Figure 3 As shown, in this embodiment, the separation barrel 2 is mounted on the base frame 1 via a double-layer support system consisting of an upper thrust bearing 11 and a lower thrust bearing 12. A limit ring 21 is provided at the top of the outer wall of the separation barrel 2. The upper thrust bearing 11 is arranged between the top of the limit ring 21 and the base frame 1, and the lower thrust bearing 12 is arranged between the bottom of the separation barrel 2 and the base frame 1. The upper thrust bearing 11 and the lower thrust bearing 12 primarily bear the axial centrifugal force generated by the rotation of the separation barrel 2 and the dynamic pressure of the sludge mixture, ensuring smooth rotation of the separation barrel 2.

[0041] Please continue reading Figure 3In this embodiment, the drive mechanism 4 includes a drive shaft 41 fixedly mounted on the top of the protrusion 5 and coaxial with the separation barrel 2, and a drive source 42 drivingly connected to the drive shaft 41. The top end of the drive shaft 41 extends from the top of the separation barrel 2 and is rotationally connected to the base frame 1 via a bidirectional angular contact bearing. The drive source 42 is fixed to the side of the base frame 1 and is drivingly connected to the drive shaft 41 via a reduction gearbox. During startup, the output torque of the drive source 42 is amplified by the gearbox and then drives the separation barrel 2 to rotate via the drive shaft 41. During the driving process, the drive source 42 implements an intermittent forward and reverse rotation strategy (e.g., forward rotation for 30 seconds → pause for 2 seconds → reverse rotation for 30 seconds), switching the direction of the separation barrel 2 through the reverse output of the gearbox.

[0042] Specifically, the drive source 42 uses a servo motor or a variable frequency motor to achieve stepless speed adjustment from 0 to 1200 rpm through a frequency converter to match the separation requirements of different sludge concentrations. For example, when the sludge solids content is greater than 20%, the motor automatically increases the frequency to 1000 rpm to enhance the centrifugal force. At the same time, the secondary reduction of the gearbox (speed ratio 5:1) increases the output torque to 220 N·m, ensuring separation stability under high load. In low-concentration conditions, the frequency is reduced to 600 rpm to reduce overall energy consumption.

[0043] In this embodiment, a fixed support shaft 13 is coaxially disposed within the sump 511. The bottom end of the fixed support shaft 13 is fixed to the base frame 1 via bolts or welding, and the top end of the fixed support shaft 13 is rotatably connected to the top wall of the sump 511 via a bearing seat. The blocking member 32 is fixed to the fixed support shaft 13 via a connector. The fixed support shaft 13 and the drive shaft 41 form a bidirectional constraint in both directions, further improving the stability of the separation barrel 2 during rotation. During filtration, the separation barrel 2 rotates around the fixed support shaft 13, while the blocking member 32 remains stationary due to its fixation to the support shaft, forming a dynamic-static interface. As the separation barrel 2 rotates, the blocking member 32 sequentially blocks the bottom and side openings of the drainage trough 512 at intervals, triggering the diversion of the liquid flow.

[0044] like Figure 1 and Figure 3As shown, in this embodiment, sludge storage components 6 are evenly arranged along the circumferential direction on the outer wall of the separation barrel 2, and the sludge storage components 6 are arranged corresponding to the filtering portion 53. A sludge storage cavity 61 extending along the height direction of the separation barrel 2 is formed in the sludge storage component 6, and a strip-shaped slit 62 is defined between the sludge storage cavity 61 and the interior of the separation barrel 2. The separation barrel 2 is also provided with a scraper 63 closely attached to the interior thereof, the top end of the scraper 63 extending from the separation barrel 2 and fixedly connected to the base frame 1. When the separation barrel 2 rotates, solid particles are enriched toward the barrel wall under the action of centrifugal force, and the enriched sludge is pushed by the lateral liquid flow and enters the longitudinally extending sludge storage cavity 61 through the strip-shaped slit 62 between the storage cavity and the inner wall of the separation barrel 2. During this process, the scraper 63 fixed to the base frame 1 is in close contact with the inner wall of the separation barrel 2 and synchronously scrapes the barrel wall to peel off the attached sludge. The scraped sludge slides into the strip slit 62 along the wall driven by centrifugal force and enters the storage chamber for temporary storage, avoiding sludge accumulation and affecting the filtration work.

[0045] like Figure 4 As shown, in this embodiment, the cross-section of the strip-shaped slit 62 is tapered, with the small end of the strip-shaped slit 62 facing the sludge storage chamber 61. When sludge enters the slit under the action of centrifugal force, the flow channel cross-sectional area gradually decreases, the flow velocity is increased, and the high shear force generated effectively breaks up sludge clumps, preventing sludge clumps from clogging the slit. The small end of the tapered structure acts as a physical barrier to prevent sludge backflow caused by pressure fluctuations during the reversal phase.

[0046] like Figure 3 As shown, in this embodiment, the sludge storage component 6 includes a cylindrical shell 64, and the sludge storage cavity 61 is formed in the cylindrical shell 64. A column with a honeycomb structure 65 is placed in the sludge storage cavity 61, and an openable and closable airtight door 66 is also provided on the outer wall of the cylindrical shell 64.

[0047] The honeycomb structure 65 columns within the sludge storage chamber 61 form a three-dimensional filtration interface through their porous structure. This increases the sludge contact area and promotes solid-liquid separation. Furthermore, the porous structure's diversion effect guides sludge particles to orderly deposit along the honeycomb channels, preventing disordered accumulation and improving sludge dewatering efficiency. Furthermore, the honeycomb structure's mechanical support can withstand the dynamic pressure caused by centrifugal force, preventing deformation of the columnar shell 64.

[0048] During the temporary storage stage of sludge, the airtight door 66 can be opened and closed to keep the cylindrical shell 64 sealed. When the storage chamber reaches the capacity threshold, the door can be opened pneumatically or mechanically to cooperate with external cleaning equipment to realize automatic transfer of sludge.

[0049] like Figure 3As shown, in this embodiment, a cover 22 with a central through-hole is removably mounted on the top of the separation barrel 2. A liquid collection trough 14 is provided at the bottom of the base frame 1, corresponding to the drainage groove 51. A drain pipe 15 is provided on one side of the liquid collection trough 14. The central through-hole of the cover 22 allows the drive shaft 41 to pass through or the sludge mixture feed pipe to be connected. A silicone sealing ring is embedded in the edge of the cover 22, which achieves a dynamic seal through centrifugal compression when the separation barrel 2 rotates, preventing liquid splashing. When it is necessary to clean the interior of the separation barrel 2 or replace the filter assembly 3, the cover 22 can be quickly removed, balancing ease of operation with sealing reliability.

[0050] Driven by centrifugal force, the drainage groove 51 at the bottom of the separation barrel 2 throws the filtered liquid out along the drainage groove 512 with an isosceles trapezoidal cross-section. The liquid falls into the liquid collection tank 14 below the base frame 1 through the bottom opening and is discharged from the drainage pipe 15.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
